Overview and present status of the CMS Phase 1 pixel upgrade

摘要

During Run 2 of the LHC a significant luminosity increase to 2×10~(34)cm~(-2)s~(-1) is foreseen. As the innermost tracking device of CMS, the silicon pixel detector has to cope with large particle fluxes and radiation damage. To maintain the present high tracking efficiency, the current pixel detector will be replaced during an extended winter shutdown in 2016/2017. The design of the new detector is described, with a special focus on the construction and testing of the pixel modules.
